Non-formaldehyde vegetable adhesive and production process thereof

The invention discloses a non-formaldehyde vegetable adhesive. According to parts by weight, materials of the non-formaldehyde vegetable adhesive include: 30 to 50 parts of soybean, 10 to 20 parts of corn starch, 15 to 20 parts of wheat, 1 to 6 parts of sodium hydroxide, 1 to 5 parts of borax, 1 to 4 parts of potassium pyroantimonate and 30 to 50 parts of water. Mainly by utilizing the natural plants, such as wheat, corn and soybean, as main materials and then adding the auxiliary materials, such as an alkaline agent, the non-formaldehyde vegetable adhesive is prepared further by steps such as heating and mixing; compared with the prior art, the non-formaldehyde vegetable adhesive has the characteristics of high bonding strength, no hygroscopicity, no crystalline bloom, low cost, easiness and convenience in material obtainment, simplicity in production and the like, and the non-formaldehyde vegetable adhesive is suitable for sticking paper and paper products, and also can be used for sticking in the production of plywoods, sizing agents and corrugated paper and alike, and the non-formaldehyde vegetable adhesive solves the harm of formaldehyde, achieving the effects of low carbon and environment-friendliness.
